SPECIFICATICN forming part of Letters Patent No. 666,632, dated January 22, 1901. Application filed December 27, 1899. Serial No. 741,762. (No model.)

To a/ZZ whowt it may concern:

Be it known that I, WILLIAM AP. BETTEN- DORF, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Shaft-Hangers, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings and to the characters of reference marked thereon.

The object of my invention is to provide a shaft-hanger constructed of wrought-sheetmetal plates in such manner as to possess the greatest strength possible, and yet possess that degree of elasticity as to avoid pounding, to which shafting sometimes is subject, while at the same time producing a light and economical hanger. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, lFigure l is a side View of my improved hanger. Fig. 2 is a front edge view of the same. Fig. 3 is a plan view thereof. Fig. 4 is a horizontal section taken on dotted line 4 4, Fig. 1, looking in the direction indicated by the arrows. Fig. 5 is a plan view of a blank from which my improved hanger is constructed. Fig. 6 is a detail view showing the broken-away wall-plate of modied construction of my invention. Fig. 7 shows a side view of a bracket-shaped shafthanger made according to my invention adapted to be attached to a vertical support. Fig. 8 shows an edge view of a modified construction of my invention.

My invention is made from one or two wrought-steel plates, which are first cutinto templets or blanks of suitable shape and then formed, bent, and riveted to produce the hanger-frame. I prefer to use but one plate of sheet metal in the construction of the hangerframe and in such event cut the blank A from one such plate into the shape shown in dotted lines in Fig. 5.

As originally cut the templet or blank A consists of a central rectangular plate 2, having corresponding wings 3 3 extending laterally therefrom. These wings are sort of yokeshaped and each have a corresponding shaped arm 4 extending therefrom, as shown. In reducing the blank to the required shape I submit the same to the action of suitable dies and form beads 5 and 6, which bound the outer edges of the wings and the arms 4 and form one-half of the boss 7 in the transverse connecting portion of the yoke-shaped wings 3 3 and a similar boss 8 in the transverse end portion of the arm 4. These half-bosses 7 and 8 aline, and, if desired, they can by the same dies be provided with threads 9, so as to be engaged in the inished device by the usual screw-threaded gage-bolts, between the ends of which the bearing-boxes of the shaft are adjustablysupported. After thus giving the desired configuration to the wings 3 and arm 4 thereof said wings are bent to the position shown in Fig. 1 to form the side frames of the hanger., The upper portion of these side frames C O converge and meet at a point corresponding to about the horizontal plane of the upper yoke-shaped part of said side frames, and the remainder of the length of said side frames below this point of initial contact is secured flatwise together by rivets or otherwise. When thus brought flatwise together, the bosses 7 7 and 8 8 of the wings of the blank form perfect cylindrical alining sockets d and e, which may be screw-threaded or not, as desired, for the accommodation of the gage-bolts of the bearing-boxes of the shaft. .The bending of the wings 3 3 downward converts the central plate 2 into an intermediate base-plate or attaching-plate G, by means of which the hanger-frame is secured to the overhead joists or timbers. If desired, this base-plate may be reinforced by a superimposed plate g and suitable bolts or screwholes a a and b be made therein during the process of its formation.

As hereinbefore intimated, my improved hanger may be made of two sheets of platemetal. In this case the blanks or templets are each constructed similar to one of the wings and extended arm thereof, including a rectangular homogeneous plate (similar to plate 9,) from which the same projects. The wing and arm of each blank are bent to the same relative position shown in Fig. 2, and then the plates oc oo are lapped over each other, as shown in Fig. 6, and the remainder of the hanger-frame is completed, as hereinbefore described.

The beaded edges of the hanger-frame greatly increase the strength of the same,

IOO

and below the plane of the upper gage-bolt boss they form a tubular edge, the value of which as a reinforcement in mechanical construction is well recognized.

In Fig. 7 I show a bracket-shaped shafthanger frame K, which is adapted to be secured to a vertical support and the side frames of which project horizontally and are provided with an upper and a lower arm kk', each of which'is provided with alining sockets h h for the reception of the usual gage-V bolts. (Not shown.) This form of hangerframe is constructed of sheet metal suitably formed and secured together the same as hereinbefore explained, and I consider it as coming within the scope of my invention.

In Fig. 8 I show a modification ofl my invention consisting of two correspondinglyshaped side frames m and n, the upper end portions p of which are flanged sidewise to provide, one-half of the wall-plate thereof and the body of which is constructed by securing the two side frames flatwise together their entire length. I may employ this method of construction or that hereinbefore described, as desired, although it is believed the former is preferable.

It will be observed that each form of my invention comprises a shaft-hanger formed of two parts or frames which are substantial duplicates of each other in-shape and are arranged side by side in planes which are substantially transverse to the axis of' theshaft to be supported. These parts or frames are brought flatwise together and united on each side of the shaft in such manner as to form bearings for the shaft-boxings on opposite sides of the shafting In the form of my invention shown in Fig. 8 the extent to which the two parts or frames of the bearings are brought flatwise together is greater than in a construction like that shown in Figs. l and 2; but so far as the broad features of my invention are concerned the extent of such contact of the parts or frames of the hangers is not important, so long as they are in engagement on each side of the shaft-as, for instance, both above and below it.

What I claim as new isl. A shaft-hanger comprising twov parts or frames arranged side by side and in planes which are substantially transverse to the line of shafting to be supported, the said parts or frames being brought Ilatwise together and united upon opposite sides of the shafting to form bearings for the shaft-boxing.

2. A shaft-hanger comprising a base-plate, and two integral frames depending therefrom said frames being arranged side by side in planes which are substantially transverse to the axis of the shaft, and secured atwise together for a portion of their length to form a singlefbearing 3. A shaft hanger formed of two corre 'spondingly-shaped parts or frames, each having substantially the outline of the completed hanger, the said parts or frames being ar yranged side by side and in planes substantially transverse to the axis of the shaft and "secured flatwise together, and having their upper portions bent to form. abase-plate.

4. A shaft-hangerframe made of suitable Ysheet metal and consisting of a base-plate, and side frames depending therefrom which converge and meet at` a suitable distance below said screw-plate and have the remainder of their length secured flatwise Atogether.

5. A shaft-hanger frame made of suitable sheet metal and consisting of a base-plate, and homogeneous side frames depending therefrom which converge and meet at a suitable distance below said base-plate and have the remainder of their length secured iiatwise together. y 6. A shaft-hanger frame made of suitable sheet metal and consisting of a base-plate, and side frames depending therefrom, the upper portions of which are yoke-shaped and the lower portions of which form an L-shaped arm extending therefrom, said side frames being bent so as to meet at a suitable distance below said base-plate and secu red iiatwise together the remainder of their length.

7. A shaft-hanger frame made of suitable sheet metal and consisti ngofa base-plate and corresponding side frames depending therefrom the upper portion of each of which is yoke-shaped and the lower portion of which forms an L-shaped arm extending therefrom, said side frames being so shaped and bent as to meet at a suitable distance below said baseplate, and to provideby their union, alining gage-bolt sockets in the horizontal part of the said yoke-shaped portions and arms of said side frames which are secured {iatwise together.

8. A shaft-hanger frame made of suitable sheet metal and consisting of a base-plate, and side frames depending therefrom having the edges thereof beaded, which converge and meet at a suitable distance below said baseplate and have the remainder of their length secured iiatwise together.
